ed less. Sheep thrive well onit. Sinclair and others 
found that this grass, when exclusively combined 
with white clover, will support, from the second sea- 
son, five ewes and five lambs on an acre of sandy 
loam. But this grass, to thrive well, needs land not 
altogether dry, In all permanent, artificial pastures 
this Alopecurus should form one of the principal in- 
gredients, because it is so lasting and nutritive. In 
our alpine regions it would also prove prolific, and 
might convert many places there gradually into sum- 
mer-runs. It is early flowering, and likes the pres- 
ence of lime in the soil. 
Alstonia constricta, F. v. M.— Warmer parts of 
East Australia, particularly in the dry, inland dis- 
tricts. The bark of this small tree is aromatic-bitter, 
and regarded as valuable in ague, also as a general 
tonic. 
Alstreemeria pallida, Graham. —Chile. Palatable 
starch can be obtained from the root of this plant, 
which, for its loveliness alone, deserves a place in any 
garden. Thetubers of others of the numerous Alstrce- 
merias can doubtless be utilized in a similar technic 
manner, 
Althe officinalis, L.—The Real Marsh-Mallow. Eu- 
rope, North Africa, North and Middle Asia. A tall, 
perennial herb, with handsome flowers. The mucila- 
ginous root, and also the foliage, are used for medici- 
nal purposes. The plant succeeds best on damp, 
somewhat saline, soil. 
Amelanchier Botryapium, Candolle.—The Grape- 
Pear of North America. This fruit-tree attains a 
height of thirty feet. The purplish fruits are small, 
but of pleasant taste, and ripen early in the season.
